While we’re not jumping into any full on balance changes, there’s a few corrections that we wanted to make for type-fixes and other intended play. — Update notes

Version 45.0

Tiers	Changes
X-1-X Sharper Prongs	Description changed ― "Tridents can pop more Bloons." → "Can pop more Bloons with each attack."
X-2-X Tidal Chill	Description changed ― "Icey tridents are larger and can freeze Bloons." → "Icy tridents are larger and can freeze Bloons."
X-X-2 Echosense Network	Description changed ― "Increases range for all Echosense Mermonkeys. Stacks up to 5 times." → "Increases range for all Echosense Mermonkeys. Stacks up to 10 times."

“

We were cautious with initial low tier Mermonkey upgrades, but as nothing seriously unexpected came up we’ve reduced the base cost and improved the projectile lifespan which should help with issues on some higher tier upgrades. — Update notes

”

Tiers	Changes
0-0-0 base tower	Cost reduced ― $600 → $475
0-0-0 base tower 1-X-X Trident Efficiency X-1-X Sharper Prongs X-2-X Tidal Chill X-X-1 Echosense Precision and further upgrades	Trident: projectile lifespan increased ― 0.5s → 1s
2-X-X Trident Swiftness and further upgrades	Trident: projectile lifespan increased ― 0.3333s → 0.6667s
3-X-X Abyss Dweller	Trident: damage increased ― 2 → 4  Pierce buff increased ― +5% → +10%  Pierce buff correctly stacks with other pierce buffs (bug fix)

“

As the middle crosspath is currently less useful for higher tiers, we’ve upgraded Sharper Prongs to improve Tentacle pierce as well. As the main Trident’s damage falls behind and has caused annoying layer skipping for some more observant players the damage of this attack is increasing at T3 & T4. The % pierce buff is being improved at all levels since this has settled without causing too much of a stir, and finally Lord of The Abyss’s price is being greatly reduced as a heavily pierce built design it requires some single-target assistance to perform well. — Update notes

Version 46.0

“

While we were happy with Arctic Knight’s Ice Jet being a high pierce MOAB layer removal that could with other tower combinations be upgraded to a more effective full-clear, there is not currently enough varied ways of quickly dealing with White Bloon layers, so for a long cooldown based ability this heavy a weakness is too much for now. Bottom path Mermonkey is proving to be very high uptime for the strong support it provides, while still exceptional this is only seeing a light nerf for now. — Update notes

Tiers	Changes
X-4-X Arctic Knight	Ice Jet: Projectile lifespan reduced ― 15s → 10s (undocumented)
X-4-X Arctic Knight X-5-X Popseidon	Ice Jet: Projectiles pass through White or Zebra Bloons if they can't damage them, instead of destroying the projectile
2-4-0 Arctic Knight + Trident Swiftness 2-5-0 Popseidon + Trident Swiftness	Now reduces the lifespan of Ice Jet projectiles by 33% (undocumented) Note: This means the maximum travel distance of Ice Jet projectiles is now the same as without the crosspath, since this crosspath increases their projectile speed by 50%
X-5-X Popseidon	Ice Jet: Projectile lifespan reduced ― 20s → 15s (undocumented)
X-X-3 Alluring Melody X-X-4 Symphonic Resonance	Trance: Cooldown increased ― 3s → 4s Note: Does not apply to The Final Harmonic

Tiers	Changes
X-X-4 Symphonic Resonance	Trance: Can again target MOAB-Class Bloons with no small Bloons present (bug fix)

Version 47.0

“

Middle path pierce was lacking all through to T5, so pierce is now being matched to T5 across the path. Symphonic Resonance is powerful, but Alluring Melody is inconsistent for a Bloon-only stall, so pierce here is also being matched up to the same as T4. — Update notes

X-X-4 Symphonic Resonance X-X-5 The Final Harmonic	Totems should no longer be considered overclock targets (bug fix)

Version 48.0

“

Abyss Dweller is far too inconsistent before it gains the T4 ink attack, so a lot of price is being shifted up out of this update. — Update notes

0-5-1 Popseidon + Echosense Precision	Lateral Trident: Arc increased ― 45° → 60° Note: 0-5-2 unchanged at 60°

X-X-5 The Final Harmonic	Trance: No longer has tighter orbit radius ― 20 → 30

Version 49.0

“

Mermonkey’s low tiers also have early game trouble and are seeing a price shift to improve this. Riptide Champion’s damage type is being made consistent with the rest of the path to grant Mermonkey earlier Lead popping, and the rest of the path is also seeing a damage increase. For fun Echosense Network will now be able to apply to Alchemist Transformed Mermonkeys, and Alluring Melody’s DoT Detonation mechanic can now apply to any targets that are already tranced although the damage cap per detonation has been reduced to compensate for this. — Update notes

“

Abyssal Warrior will now have a slight startup cooldown to limit certain exploity tactics. Middle crosspath trident gains extra projectile pierce to improve early game value. Recent changes to Symphonic Resonance caused its pierce usage to increase for far too much of a nerf, so we have increased the pierce to offset this. — Update notes

Version 51.0

Mermonkey weren’t[sic] feeling they favoured their natural habitat enough, so their Water Placement bonus is getting a boost. Middle Path Mermonkey just isn’t putting in the work we hoped, so we’re giving a couple price adjustments, a pierce increase across all tiers, and some light ability improvements to make it feel more rewarding. — Update notes

Last update many players felt blindsided when Brickell stopped applying her buff to Mermonkeys since there was no mention in the balance changes section. We would like to apologize for that - it was tasked internally as a bug as it was indeed unintended to work that way. We then left the issue alone for a long time, mostly due to other more pressing matters, and this issue fell through the cracks. In retrospect, it would have been better to treat this as balance rather than a simple bug fix due to how much time had passed. Reading through your feedback, we did consider just reverting the change, however the bigger issue that the feedback reinforced to us was that players considered Mermonkey to be so bad that it was only a "good" tower when used in combination with a single, water-only hero. This sort of forced synergy goes against our design intentions - namely that Mermonkey being our signature amphibious tower should be able to stand on its own without being balance-locked to an interaction with a single hero. With all that in mind, we feel Mermonkey's highest priority right now is large sweeping buffs to each of the paths, so most of the following changes are our first step towards this starting from the low tier crosspaths. — Update notes

Version 53.0

“

Top path Mermonkey’s pierce scaled up more than intended from applying its own pierce buff to its own already high pierce so this is being reduced but the T5 Lord of the Abyss will now gain a slight base range increase. Riptide Champion as an underappreciated star performed exceptionally well with recent changes which are now being scaled back, and Popseidon which was also performing extremely well will likewise be scaled back. Echosense's previous change was quite an overbuff and many players felt this invalidated the water placement bonuses so we are lowering this again but not all the way back. — Update notes
